Spectral imaging is imaging that uses multiple bands across the electromagnetic spectrum. [1] . While an ordinary camera captures light across three wavelength bands in the visible spectrum, red, green, and blue (RGB), spectral imaging encompasses a wide variety of …

2022年3月16日 · In this article, we review state-of-the-art deep-learning-empowered computational spectral imaging methods. They are further divided into amplitude-coded, phase-coded, and wavelength-coded...

Spectral imaging extends the capabilities of biological and clinical studies to simultaneously study multiple features such as organelles and proteins qualitatively and quantitatively. Spectral imaging combines two well-known scientific methodologies, namely spectroscopy and imaging, to provide a new advantageous tool.

Unlike a typical image, which is acquired over the entire wavelength response band of the detector, a spectral image requires the creation of a three-dimensional data set that contains a collection of images of the same viewfield captured at different wavelengths or wavebands.

2025年1月28日 · Similarly, for LIBS technique, we selected one spectral line for each relevant chemical element (Table 1, with resulting images and typical spectrum in the supplementary material). The intensities ...

2024年3月1日 · Spectral imaging reconstruction primarily aims to use neural networks to restore low-quality spectral images to high-quality ones. This process includes tasks such as artifact removal, noise reduction, and resolution enhancement.

2012年1月1日 · Spectral imaging is a relatively new field in which the advantages of optical spectroscopy as an analytical tool are combined with the power of object visualization as obtained by optical imaging; it creates a three-dimensional data set that contains many images of the same object, where each one of them is measured at a different wavelength.

2020年9月18日 · Here, we propose and experimentally demonstrate a snapshot spectral imager using a parallel optical processing paradigm based on arrays of metasystems. Our multi-aperture spectral imager weighs less than 20 mg and simultaneously acquires 20 image channels across the 795- to 980-nm spectral region.

2025年1月28日 · Hyperspectral images are images with rich spatial and spectral information obtained by a hyperspectral imaging spectrometer. Compared with ordinary remote sensing images, hyperspectral images have ...
